Eiseman, Charles S., Lonsdale, Owen & Feldman, Tracy S., 2019, Nine new species of Agromyzidae from North Carolina, USA, with new host and distribution records for additional species, Zootaxa 4571 (3), pp. 301-333 : 316

Phytomyza plantaginis Robineau-Desvoidy

( Figs. 25 , 40 )

Material examined. NORTH CAROLINA : Scotland Co., Laurinburg , St. Andrews University, 2.v.2017, em. 18.v.2017, T.S. Feldman, ex Plantago wrightiana , # CSE3686 , CNC939743 (1♀) .

Hosts. Plantaginaceae : Plantago lanceolata L., P. major L. ( Spencer 1969), P. * wrightiana Decne. TSF has found leaf mines consistent with Phytomyza plantaginis on Plantago rugelii Decne.

Leaf mine. ( Fig. 40 ) Long, narrow, white, linear; frass in large, widely spaced grains.

Puparium. Whitish; formed within the leaf, with the anterior spiracles projecting through the epidermis.

Distribution. Widespread through most of the USA; Canada: AB ( Sehgal 1971), ON, QC ( Spencer 1969); Europe; Japan; Australia; New Zealand ( Spencer & Steyskal 1986).

Comments. Although females of Phytomyza plantaginis cannot always be distinguished with certainty from those of the European P. griffithsi Spencer , the mine of that species is clearly different, consisting of numerous branches radiating from the petiole ( Ellis 2018).
